My Dad is on oxygen all the time (pulls an oxygen bottle with him). We were wondering how strenuous the Cozumel Ruins & Beach Tour is? Is there a lot of rough terrain, a lot of walking etc.? He can take some walking, etc. but now a lot of strenuous climbing, steep terrain, etc.
) so has anyone gone?will he learn anything or are the ruins just like a pile of rocks. How long are you there? And how about the beach? thanks Ann
